The DFK‑1G/-2G electric valve controller is a wall‑mounted control box designed to open and close electric valve actuators. It uses low‑voltage DC control, offers clear status LEDs, and includes safety alarms for overload or motor overheating.
The manual covers front‑panel functions, internal wiring, working principles, and step‑by‑step installation and adjustment procedures, allowing users to set up local or remote control, adjust the opening display, and verify correct operation. This manual is written in Chinese.
| Operating voltage | 220 V / 50 Hz |
|---|---|
| Control voltage | 380 V / 50 Hz |
| Control power | 1 kW |
| Operating temperature range | -20 °C to 40 °C |
| Maximum relative humidity | ≤ 80 % (at 20 ± 5 °C) |
Use the 现场/远控旋钮 to select the working mode; the local light turns on for local control and the remote light turns on for remote control.
The green valve‑open light flashes while opening and stays solid when fully open; the yellow valve‑close light behaves similarly for closing; the red accident light indicates overload or torque fault.
Turn the adjustment potentiometer until the opening display reads 100 % when the valve is at its fully‑open position.
The controller can operate in ambient temperatures from –20 °C up to 40 °C.
